CachyOS Overview

CachyOS, an Arch Linux-based distribution, is engineered for speed and security. Its optimized Linux kernel utilizes the BORE (Burst-Oriented Response Enhancer) scheduler, and desktop packages are compiled with LTO (Link Time Optimization), x86-64-v3 and x86-64-v4 optimizations, along with various security enhancements.

Key Features

• High-Performance Kernel: The BORE scheduler optimizes kernel performance.
• Optimized Software Packages: Desktop applications benefit from advanced compilation techniques for efficiency and security.

Installation is available via graphical and command-line installers.

What's New in the June 2024 Release

This latest CachyOS edition includes substantial improvements:

T2 MacBook Support

The default edition now supports T2 MacBooks. While Wi-Fi and Bluetooth require post-installation configuration due to Apple's closed-source firmware, detailed instructions are provided.

New "cachy-chroot" Script

The ISO incorporates the cachy-chroot script, simplifying the chroot process and partition mounting. It also detects BTRFS subvolumes. The ISO utilizes the mkinitcpio microcode hook and supports copytoram for faster performance (sufficient RAM required). Ventoy 1.0.98 or later is needed.

NVIDIA Graphics Enhancements

Default service enablement ensures proper sleep functionality and applies NVReg settings to resolve Wayland sleep issues. The new NVIDIA 555 driver supports explicit sync, significantly improving the Wayland experience. Compositors have been updated for explicit sync compatibility.

BTRFS as the Default Filesystem

BTRFS replaces XFS as the default filesystem, although alternative filesystems remain configurable.

UFW Replaces Firewalld

UFW (Uncomplicated Firewall) replaces firewalld, providing a simpler configuration for most users.

Handheld Edition Updates

The Handheld Edition offers improved stability, enhanced hardware detection, and configuration for devices like the Steam Deck, Legion Go, and ROG Ally. Ayaneo support is anticipated but untested.

Updated CachyOS Wiki

The CachyOS wiki has undergone a complete restructuring for improved user information.
